Sitting Bull (Tatanka Iyotake) was a Hunkpapa Lakota holy man and tribal chief who became a symbol of Native American resistance to U.S. government expansion. He is best known for uniting several tribes at the Battle of the Little Bighorn, where they achieved a stunning victory over Lieutenant Colonel George A. Custer’s 7th Cavalry. Before the battle, Sitting Bull performed a Sun Dance where he had a vision of 'soldiers falling into camp like grasshoppers,' which bolstered the warriors' morale. Despite the victory, the subsequent military crackdown forced him to flee to Canada before eventually returning and surrendering in 1881. In his later years, he briefly performed in Buffalo Bill’s Wild West show, where he used his earnings to support his people. He was tragically killed by Indian agency police in 1890 during an attempt to arrest him amidst the Ghost Dance movement, but he remains a legendary figure of defiance and cultural preservation.
